Well, there is this Psychology's field that is called Evolutionary Psychology. I admit it, some 'scientists' like it, but it's generally based in stupid generalizations, 'studies' never properly done, and the likes. Completely ignores cultures, environment, etc. In my words, it's bullshit. http://www.google.com/search?hl=en&q=evo-psych+science&btnG=Search the results on the first page were pretty amusing.

Anyway, all the things about 'nice people won't reproduce' and 'intelligence is genetic' (which is PROVED that is bullshit since most studies about IQ give higher results in areas more industrialized and the likes, and we all know intelligence is malleable) is Evo Psych talk. There.

(And as you can imagine, is one of the most sexist, racist fields out there.)
